Ice thickness measurement sensor

摘要

An ice thickness measurement sensor 100 is provided to measure the thickness of ice extending from a circuit. The ice thickness measurement sensor comprises at least one capacitive sensor 150. The capacitance of the sensor 150 depends on the thickness of ice covering the sensor, because the presence of the ice changes the permittivity. The ice thickness measurement sensor may be used in a fluid pipe, for example to measure the thickness of ice extending from the inner surface of the pipe.
